When returning arrays of primitives (
DoubleArray,BooleanArray,BigIntArray) from Java, we usedgetRegionfrom the primitive array to copy it directly into thestd::vector::data().The problem with that is that
data()will not be properly sized in our case because we usedstd::vector::reserve(..)beforehand - instead of constructing thestd::vectorwith a fixed size already.This PR fixes that.
